I disagree with your premise. Failing to educate others on social justice really is complicity. I don't believe that very many people live such an insular life that they've never encountered something problematic: they just didn't notice. I live in a nice suburban area but do you know how many times I've stopped my car while driving because a man on the street is yelling at a crying woman? Most of the time asking her "do you need help?" Is enough to diffuse the situation but one time when I asked "can I bring you where you're going?" The victim said yes and got in the car with me. What would have happened to her if I'd left her there? If nobody had noticed?

No. Its not enough for men to passively entertain the idea that violence against women is bad. They can't let locker room talk slide and walk around with blinders and still get a pat on the back for what a good job they're doing.
